We look at the division of 34090586 by 642 
We're looking to find how many times 642 goes into 34090586.

Step 1:
When dividing 3 by 642, we get 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 642

Going ahead to step 2:
If we divide 34 by 642, we get 0 and a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 34 after subtracting 0 from 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 642

Moving on to step 3:
642 goes into 340 0 times with a remainder of 340.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 340 to get 340.
Include the next digit (9) from the dividend after 340, then repeat: 3409 / 642

Step 4:
When dividing 3409 by 642, we get 5 with a remainder of 199.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 3210 from 3409 and we're left with 199.
Grab the next digit (0) from the dividend, add it to 199, then carry on: 1990 / 642

Moving on to step 5:
If we divide 1990 by 642, we get 3 and a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 53.0
The remainder is 64 after subtracting 1926 from 1990.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 642

Moving on to step 6:
642 goes into 645 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 531.0
If we take 642 away from 645, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 642

Advancing to step 7:
The number 642 fits into 38 0 times, leaving a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 5310.0
If we take 0 away from 38, we end up with 38.
Fetch the next digit (6) from the dividend, attach it to 38 and continue: 386 / 642

Step 8:
When dividing 386 by 642, we get 0 with a remainder of 386.
Put 0 as the next digit of the answer. 
Result so far: 53100.0
Subtracting 0 from 386 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Step 9:
642 can be fit into 3860 6 times, resulting in a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 53100.6
Subtract 3852 from 3860 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
80 divided by 642 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 53100.6
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 11:
If we divide 800 by 642, we get 1 and a remainder of 158.
Write down 1 as next digit of the result. 
Result so far: 53100.601
Deduct 642 from 800 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Step 12:
The number 642 fits into 1580 2 times, leaving a remainder of 296.
The next digit of our result is 2. 
Result so far: 53100.6012
Deduct 1284 from 1580 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Step 13:
642 goes into 2960 4 times with a remainder of 392.
Use 4 as the next digit of our solution. 
Result so far: 53100.60124
If we take 2568 away from 2960, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

On to step 14:
3920 divided by 642 is 6 with a remainder of 68.
Put 6 as the next digit of the answer. 
Result so far: 53100.601246
Deduct 3852 from 3920 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 15:
642 goes into 680 1 times with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 53100.6012461
Subtract 642 from 680 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 16:
642 goes into 380 0 times with a remainder of 380.
The next digit of our result is 0. 
Result so far: 53100.6012461
Deduct 0 from 380 and we're left with 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final outcome is 53100.6012461, with a leftover of 3.8e-07.
